WesternActor writes: Computers are getting cheaper to buy every year, but there are still sometimes advantages to building them yourself. ExtremeTech has a story about how they sought out the parts for a $200 computer that (of course) runs Linux as a way of breaking the budget barrier. They even test it against a commercially available eMachines nettop to see how it compares in terms of performance. This probably isn't something everyone will want to do, but it's an interesting example of something you can do on the cheap if you put your mind to it.
